🤔 Have questions?
Here are the answers to the most common questions from my clients. If you can't find your answer, feel free to contact me directly!
01What are your rates for a React developer?
My rates range from €400 to €550/day depending on the project complexity. I always offer a free quote within 24h and packages for long-term missions. My rates include maintenance and post-delivery support.
02How long does it take to develop a mobile application?
An MVP (Minimum Viable Product) takes 4 to 8 weeks with React Native. A full project (e-commerce, SaaS) may take 3 to 6 months. I always meet announced deadlines thanks to a proven agile methodology.
03Is working with a freelancer secure?
Yes! I sign a service contract with a confidentiality clause. You retain intellectual property of the code. I also offer 3 months of included post-delivery support and a satisfaction guarantee.
04What is your area of operation?
I work in France, Belgium and Switzerland (on-site or remotely) depending on your needs.
05Do you offer React/TypeScript training?
Yes, I train your teams on React, TypeScript and React Native best practices. Rate: €1,200/day for a group session (max 5 people). Certified training available with included educational materials.
06How to optimize SEO for a site built with Astro.js?
Astro.js generates static HTML, ideal for SEO. I also configure dynamic meta tags, sitemaps, rich snippets, and Core Web Vitals optimization to maximize your visibility on Google.
07Do you have experience with e-commerce APIs?
Yes, I've worked on integrations with Shopify, Magento, PrestaShop, WooCommerce and custom APIs (e.g., stock synchronization for Carrefour, Stripe/PayPal payment systems).
08What is the difference between a full-stack and front-end developer?
A full-stack developer (like me) masters both the front-end (React, TypeScript, UI/UX) and the back-end (Node.js, Python, databases). A front-end developer focuses only on the user interface.
09What are the advantages of React Native for a mobile app?
React Native allows you to develop an iOS and Android app with a single codebase, reducing costs by 60%. Native performance, access to phone features, and simplified maintenance. Used by Facebook, Instagram, Uber.
10Do you offer maintenance and support after delivery?
Yes, I offer 3 plans: Basic support (bug fixes), Evolutionary maintenance (new features), or Full support (monitoring + optimizations). 6-month to 3-year contracts available.
11How do you guarantee code quality?
I use best practices: automated testing, code review, TypeScript for safety, ESLint/Prettier, CI/CD with GitHub Actions. Each deliverable goes through a 50-point quality checklist.
12Do you work with startups and SMEs?
Absolutely! I support startups from MVP to scale-up. Preferential rates for young businesses, installment payment options, and included strategic advice. Over 20 startups supported.
